Provided is an optical receptacle () having an installation plane (), an optical plane, and a reference plane (). An inclination angle of the reference plane () with respect to the installation plane () is smaller than an inclination angle of the optical plane with respect to the installation plane (). Then, a first inclination angle &#x3b8;that is the inclination angle of the reference plane () with respect to the installation plane () and a second inclination angle &#x3b8;that is an inclination angle of the optical plane with respect to the reference plane () are measured. Then, the first inclination angle &#x3b8;is added to the second inclination angle &#x3b8;to calculate a third inclination angle &#x3b8;that is the inclination angle of the optical plane with respect to the installation plane ().

Measurement method and optical receptacle

In an embodiment, an optical receptacle includes a first lens face that is disposed on a first surfaceon a photoelectric conversion deviceside in an optical receptacle main body so that a portion of light of the light of a light-emitting elementis incident thereon, a first reflective surfacethat is disposed on a second surfaceon the side opposite to the first surfaceand reflects the light that has been incident on the first lens face, and a second reflective surfacethat is disposed on the first surfacecontinuously with the first lens faceso that a remaining portion of light of the light of the light-emitting elementis incident thereon and reflects the incident remaining portion of light towards a light-receiving elementas monitor light are included.

Lens array and optical module including the same

As a result of a fourth surface being a surface on a gate side, a merging position of a molten resin material during molding of a lens array main body is placed away from formation positions of lens faces, and as a result of the three dimensional shape of a third recessing section, during molding of the lens array main body, the flow of molten resin material from a surface side that opposes the fourth surface into a flow path corresponding with an area between a first recessing section and a second recessing section can be suppressed.

Lens array and manufacturing method thereof

An optical receptacle disposed between a photoelectric conversion device and an optical fiber includes a light separating section for separating incident light into monitor light and fiber coupled light, which section includes a segmented reflective surface and a segmented transmitting surface. The reflective surface for reflecting light as monitor light is disposed in a segmented manner with spaces in a segmentation direction. The transmitting surface is disposed in a segmented manner in areas where the reflective surface is not disposed, so as to transmit a portion of light other than the reflected light in a direction directly oppose to the direction of the reflected light and to advance the other portion of light towards the side of an end face of the optical fiber.
